Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed November 12, 1904. Serial llo 232,469.

To aZZ whmn it natty concern.

Be it known that I, ELIJAH C. HALL, a citizen of the United States,residing in Brain tree, in the county of Norfolk and State ofMassachusetts, have invented an Improvement in Hinges, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention relates to blind-hinges, and has for its object toprovide a hinge of a construction, as will be described, whereby theblind is securely locked in its closed or open position by the hingeuntil positively unlocked by longitudinal movement of the blind. Forthis purpose the hinge is provided with one member which is attached tothe house or window-casing and is provided with a pintle having anon-circular section which is adapted to it in a correspondinglyshapedsection of the other member of the hinge and prevent rotary movement ofsaid second member until said second member, which is attached to theblind, is moved longitudinally to bring an enlarged section of itssocket into cooperation with said non-circular section of the pintle topermit the blind to be revolved, as will be described more fullyhereinafter. Provision is also made for preventing the blind frombeingaccidentally unhinged, as will be described.

These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 is a front elevation of a blind provided with hinges embodyingthis invention, the blind being shown in its closed position; Fig. 2, aside elevation of the blind shown in Fig. 1 looking toward the right;Fig. 3, a detail to be referred to; Fig. 4, a front elevation of theblind in its open and raised position,

and Figs. 5, 6, and 7 sectional details to be referred to.

Referring to the drawings, a represents a blind which is hung to thecasing b by hinges embodying this invention.

In accordance with this invention each hinge is composed of one member0, which is attached to the house or casing b, and a cooperating memberd, which is secured to the blind.

Referring to Figs. 2, 5, 6, and 7, the member c is provided with a screwor spur 12, adapted to be forced into the house or casing b, and apintle 13, which is adapted to enter the socketed member (1, attached tothe blind.

The pintle 13 is provided intermediate its ends with a non-circular andpreferably rectangular section 16 and above and below the same withcircular sections 17 18, the bottom or lower portion 19 of the pintlebeing also non-circular in cross-section. The noncir cular sections 1619 of the pintle are designed to fit correspondingly-shaped sections 2021 in the socketed member d, and above and be low the non-circularsection 20 of the socketed member the said member is provided withenlarged circular portions 22 23 of a diameter sufficient to permit thesocketed member to rotate freely about the pintle.

In the normal or lowered position of the socketed member of the hingethe non-circularportions 20 21 cooperate'with the noncircular portions16 19 of the pintle, as shown in Fig. 5, and when in this position thesocketed member is incapable of being rotated, and the blind is therebylocked from turning. If it is desired to turn the blind from its closedto its open position, or vice versa, the socketed member of the hinge ismoved longitudinally of the pintle until the noncir cular portions 20 21are engaged with or brought into the same horizontal plane as thecircular portions 17 18 of the pintle, which position is represented inFigs. 4 and 6, and when in this position the socketed member of thehinge and the blind may be rotated or turned about the pintle, so as toopen or close the blind, as the case may be.

Provision is made to limit the longitudina movement of the socketedmember on the pintle, and for this purpose the pintle is provided with alip or projection 30, which cooperates with a shoulder 31, constitutingthe bottom Wall of the enlarged section 22 and extended around the saidsection on three sides, leaving the fourth sideplain and extended to themouth of the socketed member, as represented in Fig. 7, so that when theplain side wall of the socket in the sock- .eted member is brought intoline with the lip or projection 30 the socketed member can be removedfrom the pintle and the blind unclosed position, after which the blindmay be lowered still further and into the position shown in Fig. 5,wherein it will be seen that the non-circular portions 20 21 of thesocketed member engage the non-circular portions 1.6 19 of the pintleand securely lock the socketed member from. turning, thereby firmlyholding the blind in either its closed or open position and preventingor reducing to a minimum rattling of the blind.

Provision is made for elevating the blind, and for this purpose I haveshown one form of device,(see Figs. 1 and 8,) which consists of a lever,preferably made of a wire rod, which is provided with one or more coils40, through which is passed a staple 41 the coil constituting a pivotfor the lifting-lever, one arm 42 of which is provided with alinger-piece 43 and the other arm of which is provided with asubstantially horizontal coil 44 to engage the under side of the blindin its closed position, (see Fig. 1,) the said arm being extended beyondthe coil 44 and provided with a linger 46 to engage the under side oi.the blind in its open posit on. (See Fig. 4.)

By reference to Fig. 3 it will be seen that the linger 43 extendslaterally beyond the blind in both directions, so that the liftinglevermay be operated from the inside or outside of the house with the blindclosed.

In Fig. 4 the blind is shown in its open position and as raised, thelilting-lever being in its depressed position.

I have herein shown one form of lifting device; but I do not desire tolimit my invention in this respect. I may prefer to employ twonon-circular sections 16 19 on the pintle but, if desired, the section19 may be made circular in form.

I claim 1. In a hinge, in combination, a member provided with a pintlehaving a non-circular section and a circular section, and a cooperatingsocketed member provided with a noncircular section to cooperate withthe noneircular section of the pintle and lock the socketed member fromturning, and having an enlarged section to cooperate with thenon-circular section of said pintle to 'permit the socketed member toturn, substantially as described.

2. In a hinge, in combination, a member provided with a pintle having anon-circular section and a circular section, a cooperating socketedmember provided with a non-circu lar section to cooperate with thenon-circular section of the pintle and lock the socketed member fromturning, and having an enlarged section to cooperate with thenoncircular section of said pintle to permit the socketed member toturn, a lip or projection on the circular section, and a shoulder in thesocketed member, substantially as described.

3. In a hinge, in combination, a stationary member provided with apintle having a noncircular section intermediate its ends, and a movablesocketed member closed at its upper end and provided with a non-circularsection cooperating with the non-circular section of the pintle to lockthe socketed memher from turning and having an enlarged section tocooperate with the non-circular section of said pintle to permit thesocketed member to turn, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ELIJAH C. HALL.
